Yama Tsukami

Description

This floating Elder Dragon is colossal enough to have an ecosystem
of flora living on it. It consumes the earth and swallows forests
whole as it wanders in search of rich soil.

Attacks foes by forcefully expelling Thunderbugs and Dracophage
Bugs from its body. The expelled Thunderbugs are highly unstable
and will explode at the slightest touch.

Although wingless, Yama Tsukami can still float via internal gases.
It ingests vast amounts of soil and rotted carrion, which in turn
release gases that allow it to float for long periods of time.
